METALLIC CEILING OR SHEATHING.

Specication of Letters Patent.

Patented Feb. 1s, 190e.

Application filed December 7. 1907. Serial No. 405x492- To all whom tt may concern:

Be it known that l, PETER EBNER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Metallic Ceilings or Sheathing, of which the following is a specification.

lly invention relates to the improvement of metallic ceilings or sheathing and the objects of'my invention are to provide an im- -proved construction of metallic sheathing or ceiling panels wherein is embodied improved means for locking the panels of each row into engagement with each other; to so construct and arrange the locking means as to admit of the lock connection between the panels be- `ing readily produced either before or after the panels are united with" the furring strips or supporting framework; to provide improved means for connecting the panel supporting framework with metallic beams such as are usually used in the construction of vaults or other fire-proof structures and to produce other improvements the details of which will be more fully pointedout hereinafter.

These objects I accomplish in the manner illustrated. in the accompanying drawing, in which:

Figure 1 is an underside view of four ceiling panels having my improved construction, Fig. 2 is an enlarged sectional view on line --x of Fig. 1, showing in addition thereto a continuation of the section through the corner plate or cove and through a portion of one of the wall panels, Fig. 3 is a view in perspective illustrating the means which l eme ploy for connecting the fmurring strips with metal ceiling beams, Fig. 4 is a face view showing a portion of a furring strip and means connected therewith for securing the same to a wall, Fig. 5 is a detail view in per spective of the furring strip attaching device shown in Fig. 4, Fig. 6 is a detail sectional view on line g4] of Fig. 1, and Fig. 7 is an.

underside view of the outer portion of one of the ceiling panels.

` Similar numerals refer to similar parts throughout the several views.

1 represents sheet metal panels of that character which are designed to be used in the construction of sheet metal ceilings or side walls, these panels being cut and stamped to the required sizes and suitably embossed or ornamented when desired. In the construction of each of the panels 1, one side thereof is bent rearward or upward forming an edge tongue or flange l, which in its outer portion is curved inward and thence outward as indicated at 1b. The opposite edge of each of the panels 1 with the exception of those panels which lie adjacent to the sides of the room and which l have given the additional numeral. of lC in the drawing, is formed with an upwardly projecting ortion which is bent downward upon'itse f to form a loop which is indicated at 2. elongated loop projection is of such width in its lower portion as to present a compara tively narrow entrance slit and in the joining of two adjacent panels, the curved tongue 1D of one panel is forced through said narrow openingand into the loop of the adjacent panel, thereby springing the outer member of the loop slightly outward and causing the outer edgeportion of the tongue upper portion ofthe latter. This engagement in conjunction with the pressure on the tongue of the outer member of the loop, serves to form a desirable detachable locking connection of adjoining panels, which lock ing connection can be produced either before the panels are placed in their position against the ceiling framework or afterward.

It will be understood that the above described method of connecting the anels can be carried out through one row ofD panels at when similarly united are connecter with the first mentioned row by causing their adjacent edges to overlap each other in the manner indicated in Fig. 6 of the drawing, said overlapping portions being suitably nailed to the furring strips 3 which are secured at pro er intervals to the ceiling framework. t will be observed by reference to Fig. 7 of the drawing, that the loop 2 is not of such length as to extend to the ends of thejpanel (which is also true of the tongue 1b) thus providing a space between the ends of the loops and tongues of two adjoining panels for the free passage of the furring strip.

In the constructionof the furring strips 3, I ordinarily em loy the usual wooden bars or frame pieces, tlie samevbeing first covered with a sheet metal sheathing or casing as indicated at 4.

As indicated in Figs. 1 and 2 of the drawing, the outer edges of those ceiling panels 1" which are nearest the side walls of the This to engage the inner surface of the loop in thel a time and that the adjoining rows of anelsV i of the flanges 1WL of the beam l0.

room, are formed without the loop 2, the edge portions of said panels being in the nature of a horizontal flange such as is indicated at 1d. These Hanges 1d are connected with a suitable filling strip 5 which is suitably secured to the undersides of the furring strips and which has its outer portion connected, as shown in Fig. 2 of the drawing, with the upper portion of an inclined corner plate or cove 6. This cove plate or strip is intended to cover the junction of the ceiling and side walls of a room and has its lower end portion turned outwardly as indicated at 6, said outturned portion being suitably secured to the tops of vertical or side wall furring strips 7 to the outer faces of which are secured side wall metallic panels 8. In attaching the furring strips to the side wall of the room, I employ at desirable intervals attaching devices such as are indicated at 9 in Figs. 2, 3 and 5. This attaching device or clip consists in a sheet metal body having opposing tongues 9u which are formed with forwardly bent side wings 9b. The clip 9 further consists in oppositely projecting central wall attaching tongues 9C. The body of the clip 9 is adapted to engage the rear side of a furring strip, while the sides of the latter are embraced by the wings 9b. The tongues 9C are adapted to receive attaching nails which may be driven into the side wall or its framework and the central portion of the clip body may, if desired, be nailed to the rear side of the furring strip. The side wall furring strips, as prescribed for those of the ceiling, are covered with a sheathing or casing such as indicated at 7a.

In Fig. 3 of the drawing, I have shown a portion of a metallic ceiling beam which is indicated at 10, this beam being of that character which is ordinarily employed in the construction of the ceiling framework of a vault or other .[ireproof structure. Owing to the difficulty of attaching the furring strips to the flanged lower side of those metal beams by nailing, I employ the attaching clamps which are indicated at l1. Each of these clamps comprises a channel-like body preferably ofv sheet metal, the downturned opposing sides llil of which have formed in corresponding ends, recesses 11b which are adapted to receive the greater portion of one rlhe clamps 11 are strengthened by having the central portion of their upper sides bent upwardly to form a rib or channeled portion which is indicated at 11C. The side pieces 11a of the clamp are secured by nails 12, or by other suitable att-aching devices, to the sides of the covered furring strip 3 and when two of these' clamping pieces are thus secured to the furring strip in such position that the o ppositely projecting portions l()a of the base flange enter the recesses 11b, it is evident that the furring strip will be securely anchored to the metal beam.

In connecting a furring strip with two other furring strip sections which extend at vright angles therewith, I may employ the construction also illustrated at the left in F 3, in which the ends of the two transverse furring strips which I have indicated at 3a and which abut against the sides of the strip 3, are supported. in the oppositely pro-A jecting socket members' 13 of a coupling body 14. This coupling body is formed of sheet metal and is provided at its central portion with projecting channel-like members 15 which are adapted to embrace the bottom and opposite sides of the stripl 3 to which said coupling body is secured.

l. In a metallic ceiling and sheathing construction, the combination with interlocked ceiling panels, and means for attaching said panels to a ceiling framework7 of a corner or cove member, vertical side wall furring strips, the upper ends of which meet and support the lower portion of said cove member, and ceiling filling strips which connect the outer ceiling panels with said cove member.

2. In a metal ceiling and sheathing construction, the combination with metal ceiling beams having flanged bases, and furring strips intersecting said ceiling 1beams at right angles, of metal clamping members compris-V ing channel shaped bodies formed with end recesses in their side portions, said end recesses being adapted to receive the base flanges of said metal beams, and the sides of the clamping bodies being adapted to be secured to the sides of the furring strips.

In testimony whereof I afi-ix my signature in presence of two witnesses.

PETER EBNER. `Witnesses:
